Answer:
82
Step-by-step explanation
To find the number you divide 98.4 by 1.2
Answer:
.
Step-by-step explanation:
1^3 + 2^3 + 3^3=
1 + 8 + 27 =
9 + 27 = 36
17/20 because it would be 85/100 and 5 goes into 85 17 times and 5 goes into 100 20 times.
Substituting for r and h:-
volume = pi (x - 3)^2 * (2x + 7)
= pi* (2x + 7)(x^2 - 6x + 9)
= pi * (2x^3 - 12x^2 + 18x + 7x^2 - 42x + 63)
= (2x^3 - 5x^2 - 24x + 63) pi answer
